One of a number of versions, the 1669 Fundamental Constitutions was a theoretical instrument of rule. These documents, attributed to the young philosopher John Locke, provided for a feudal system in the new colony, with colonial nobility carrying hereditary titles such as “cacique” and “landgrave,” and the eight proprietors forming the highest level of rule. It was adopted in March 1669 by the eight Lords Proprietor of the Province of Carolina.
